Where a statute provides for a thing to be done in a particular manner, then it has to be done in that manner, and in no other manner

It is well settled that where a statute provides for a thing to be done in a particular manner, then it has to be done in that manner, and in no other manner, vide Chandra Kishore Jha vs. Mahavir Prasad, AIR 1999 SC 3558 (para 12), Dhananjaya Reddy vs. State of Karnataka, AIR 2001 SC 1512 (para 22), etc. Section 86(1)(f) provides a special manner of making references to an arbitrator in disputes between a licensee and a generating company. Hence by implication all other methods are barred.
